Question

我有2个独立的JSON文件，一个存储用户ID和“现金”，另一个存储用户ID和“城市”。我将它们存储在单独的JSON文件中的原因是为了防止错误，它只会丢失部分数据。

在排行榜上，我试图显示用户拥有的现金量以及他们来自哪个城市。现在，代码给了我一个关键错误：

File "c:\Users\test\Desktop\testclone\TESTCLONE.py", line 2411, in on_message msg += '{0}. <@!{1}> {2} Dollars\n\n'.format(number +1, user, cash[user].get('dollars', 0)) + '\nCity: **{}**'.format(homecity[user].get('city',0)) KeyError: '244410964693221377'

此外，我尝试仅将城市显示为嵌入对象，并且我敢肯定，即使我没有遇到键盘错误，也不会抓住与现金最多的用户相关的城市。如果JSON文件“现金”也没有存储城市，是否可以做我想做的事？

try:
    with open("homecity.json") as fp:
        homecity = json.load(fp)
except Exception:
    homecity = {}

def save_homecity():
    with open("homecity.json", "w+") as fp:
        json.dump(homecity, fp, sort_keys=True, indent=4)

def add_city(user: discord.User, city: str):
    id = user.id
    if id not in homecity:
        homecity[id] = {}
    homecity[id]["city"] = homecity[id].get("city", "") + city
    print("{} is now in {}".format(user.name, homecity[id]["city"]))
    save_homecity()

def get_city(user: discord.User):
    id = user.id    
    if id in homecity:
        return homecity[id].get("city", 0)
    return 0

try:
    with open("cash.json") as fp:
        cash = json.load(fp)
except Exception:
    cash = {}

def save_cash():
    with open("cash.json", "w+") as fp:
        json.dump(cash, fp, sort_keys=True, indent=4)

def add_dollars(user: discord.User, dollars: int):
    id = user.id
    if id not in cash:
        cash[id] = {}
    cash[id]["dollars"] = cash[id].get("dollars", 0) + dollars
    print("{} now has {} dollars".format(user.name, cash[id]["dollars"]))
    save_cash()

def get_dollars(user: discord.User):
    id = user.id
    if id in cash:
        return cash[id].get("dollars", 0)
    return 0

        if message.content.startswith('!lb cash'):
                cash_leaderboard = sorted(cash, key=lambda x : cash[x].get('dollars', 0), reverse=True)
                msg = ''
                for number, user in enumerate(cash_leaderboard) and enumerate(city_leaderboard):
                    msg += '{}. <@!{}> {} Dollars | **{}**\n\n'.format(number +1, user, cash[user].get('dollars', 0), homecity[user].get('city',0))
                    if number == 10:
                        break
                    else:
                        number += 1

                    embed = discord.Embed(
                    title="TOP LEADERBOARD\nLeaders:",
                    color=0x24d7cf,
                    description=msg
                )
                    embed.set_author(name="BOT", icon_url="")
                    embed.set_thumbnail(url="")
                    embed.set_footer(text="BOT", icon_url="")

                await client.send_message(message.channel, embed=embed)

大脑炸完后，我意识到我一直都知道问题的答案。我改变了

msg += '{0}. <@!{1}> {2} Dollars\n\n'\n\n'.format(number +1, user, cash[user].get('dollars', 0)) + '\nCity:, **{}**'.format(homecity[user].get('city',0))

到

msg += '{}. <@!{}> {} Dollars | **{}**\n\n'.format(number +1, user, cash[user].get('dollars', 0), homecity[user].get('city',0))
